(format "%-10s" ...) differs on character vs byte width between XEmacs
and GNU Emacs. This means that the "correct" width is lost when doing
cut operations on wide characters in the summary buffer...

...so, feel free to fix it, but if I start getting the wrong results I
will submit a patch to make it work again.

It's only really the `format' stuff that's different between the two
Emacs-en, IIRC, but I have not thought about this for ages...
